I am looking for a Software/SaaS Product, Free or Paid, which can help me setup the Affiliate system on my own SaaS product. This should assign an affiliate ID to each of users of my product, and will help in tracking any new users who gets converted because they came to us from one of our affiliates. This tracking is important to allocate the correct rewards for each referred conversion.

-Built for SaaS
-Tons of integrations
-Pricing is better than many of the competitors out there.
-Can create multiple programs (referral, VAR, agency, etc.) under one account with no extra charges.
-Team is awesome and support is quick and nice.

I know of KickRef for KickEX that is both a B2B and B2B SaaS solution. It has only recently been launched and I believe is customizable in any way to suit your software product. I would contact their team. Hope it helps!
